Hill spent the last two seasons with Toronto, but the Blue Jays removed him from their 40-man roster in October and Hill elected free agency rather than a minor league assignment with Toronto. The 31-year-old Hill has made major league appearances with four different teams over seven seasons.
He's appeared in 45 major league games in his career, including 44 starts. In 242 career innings, Hill struck out 151 batters while posting a 4.69 ERA. He spent the majority of last season pitching in Triple-A. He went 9-2 with a 4.52 ERA in 15 starts in Triple-A in 2012.
In Detroit, Hill will likely provide organizational depth. He could compete for the fifth spot in the starting rotation in spring training, but will likely start the season in Triple-A and provide insurance in case of injury.
